Document Summary

Properties from the steam tables (table a-6) and. The mass flow rate of steam is m m m. 5. 833 kg/s (b) we take nozzle as the system, which is a control volume since mass crosses the boundary. Substituting, the exit velocity of the steam is determined to be. It yields (c) the exit area of the nozzle is determined from. 2 air is an ideal gas with variable specific heats. Properties the gas constant of air is 0. 287 kpa. m3/kg. k (table a-1). Analysis (a) there is only one inlet and one exit, and thus & We take diffuser as the system, which is a control volume since mass crosses the boundary. Substituting, the exit velocity of the air is determined to be. It yields (b) the exit pressure of air is determined from the conservation of mass and the ideal gas relations, and m. 3 the device is adiabatic and thus heat transfer is negligible.
